MEANS FOR INKING PRINTING-PRESS ROLLS.

SBFGZFICATIOH forming part of Letters Patent No. 690,89 5, dated January7, 1902. Application filed February l,1901. Serial No. 45,869. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, JOHN H. SOHUSSLER, a citizen of the United States ofAmerica, residing at Denver, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements in Means forInking Printing-Press Rolls; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thecharacters of reference marked thereon ,which form a part of thisspecification.

My invention relates to improvements in ink-distributing means for theinking-rolls of printing-presses; and it consists of the featureshereinafter described and claimed, all of which will be fully understoodby reference to the accompanying drawings, in which is illustrated anembodiment thereof.

"In the drawings, Figure 1 is a side elevation of a portion of aprinting-press equipped with my improvements. Fig. 2 is a fragmentarydetail View illustrating my improved feature shown in connect-ion withthe inking-rolls and on a larger scale. Fig. 3 is afront view of thesame viewed in the direction of arrow a, Fig; 2. In this view theink-disk and truck are shown, the rolls being in the position indicatedby the upper dotted lines in Fig. 1. Fig. 4: is a detail view, partly insection, of one of the inking-rolls. Fig. 5 is an end view of the detailshown in Fig. 4. Fig. 6 is a front view of the inking-rolls shown in theposition indicated by dotted lines in Fig. l and viewed in the directionof arrow 0 and shown on a larger scale. Fig. 7 is a section taken on theline y y, Fig. 2, viewed in the direction of the arrow and on a largerscale. Fig. 8 is a detail view of an arm constituting an importantfeature of my improved construction, shown on a larger scale.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the frame of the machine; 6, the ink-disk 7,each of two of the rolls for inking the type; S, the third orsupplemental inkingroll; 9,the spring-held rods connected with therolls, and 10 the pivoted frame upon which the rods are mounted. Mountedabove and engaging both rolls 7 is a distributing-roll 12, journaled ateach extremity in a box 13, held in place by a frame 14, attached to ahook 9 of one of the rods 9. The box 13 is adjustable by means of a bolt15, threaded in the top piece of a frame 14. Mounted on oneextremityofthedistributing-roll journal, which is extended for thepurpose, as shown at 12, is a pinion 16, having flanges 16, extendingbeyond the cogged periphery and forming a circumferential groove, intowhich projects and meshes with the cogs of the pinion a cam or spiralgear 17, provided with a sleeve 17 mounted on a spindle 18, secured tothe hook 9 by a nut 19, screwed upon'the threaded extremity of thespindle. This nut is only a convenient fastening means, and the end ofthe spindle may be upset to hold the nut in place after the latter isapplied, or 7o the nut and threaded spindle extremity may be dispensedwith altogether and the spindle upset to hold it in place on the hook 9.

Mounted upon the protruding reduced extremity 8 of the journal of theroll Sis an arm 20, having a collar through which screws 21 are passedinto the hook 9. The shanks of these screws are plain, and they passthrough plain openings in the collar of the arm, whereby the latter ispermitted a sliding movement 8o on the screws, which protrude beyond thearm and are surrounded by coil-springs 22, which normally hold the armagainst the hook 9. The collar of the arm 20 is provided with aprojection 20, which passes through the hook to engagement with thehigh-tread part 23 of the truck of the roller 8. This projection extendson one side only of the collarthat is, on the side where the hook isopen. Thus the projection does not interfere with 0 the directengagement of the hook with the journal 8 of the roller 8. This truckpart 23 is longitudinally movable on the rollerjournal within certainlimits, the range of movement being indicated by the space A in 5 Fig. 4between the part 23 and the hook 9. The truck part 23 is normally heldin the position shown in Figs. 3 and 4 by the springs 22, which act onthe said part through the medium of the arm 20 and the projection 20.Each extremity of the roller 8 is equipped with a spring-actuatedslidable truck part 23;

but only one of these truck parts acts in conjunction with the arm 20,as only one arm of this character is necessary. The arm 20 is providedwith a joint 20 which allows its upper part 20 a certain range ofmovement, which becomes necessary, since its collar or lower part isprevented from turning except with the hook 9, to which it is fastenedby the screws 21, as aforesaid.

The function of the cam or spiral gear 17 and the pinion 16 is to impartan endwise movement to the roll 12 while the rolls 7 are passing overthe ink plate or disk 6, whereby the ink is evenly distributed on therollers 7. The frame is cut away, as shown at 5, for the high-tread part23 to allow the roll 8 to engage the ink-disk. Just before theinkingrolls pass to the type-surface 5 of the frame the truck parts 23move upwardly out of the grooves 5, (see upper dotted-line position inFig. 1,) whereby the roll 8 is raised sufficiently to clear thetype-surface while the rolls are moved downwardly. While the rolls arepassing over the ink-plate the upper extremity of the arm 20 engages thespindle 18 between the hook 9 and the inner extremity of the sleeve 17,whereby the sleeve is prevented. from sliding endwise on the spindle 18,and causing the endwise movement of the roll 12 through theinstrumentality of the cam-gear and pinion. As soon, however, as theroll 8 is raised by reason of the truck parts 23 traveling upwardly outof the grooves 5 the arm 20 is carried upwardly sufficiently todisengage its upper extremity from the spindle 18, thus allowing thesleeve 17 to slide endwise on the spindle 18. This result is broughtabout to a certain extent by virtue of the angular relation of the rods9 to the inking-disk and type-form. The variation of the angle formed bythe rods to the surface of the ink-disk and type-form changes theposition of bar 20, since the bar is connected with the hook of one ofthe rods 9, as aforesaid. Thejoint 20 of the bar allows the arm 20independent movement within certain limits. During this time the roll 12has no endwise movement, but simply'a rotary move-- ment on the rolls 7,since the endwise movement of the distributing-roll is not desirablewhile the rolls 7 are passing over the type-surface 5. As the threerolls pass downwardly over the type-surface the high truck parts 23engage the tracks 24 on opposite sides of the type-su rface,whereby theroll 8 is raised from said surface, while the rolls 7 both engage theprinting-surface. (See lower dotted-line position of the rolls in Fig.1.) When, however, the rolls have traveled beyond the printingsurface 5in their downward movement, the track is outwardly beveled, as shown at24:, whereby the truck parts 23 are thrown outwardly beyond the track.This action is facilitated by the spring-actuated rods 9, which pull thetruck parts 23 inwardly and force them off the track, acting inconjunction with the beveled portions 24 of the track parts.

This movement is substantially the same as set forth in my previouspatent, No. 662,880, dated November 27, 1900. As the truck parts 23 slipoff the track the one at the right (referring to Fig. 6) moves outwardlyand acting on the projection 20 imparts a corresponding movement to thearm 20 and moves it to the position shown in Fig. 6, so that as the roll8 moves to the plane of the printing-surface the arm 20 will be raisedupon the sleeve 17, thus allowing the sleeve 17 and the gear 17 tocontinue their endwise movement the same as when the arm was supportedin the raised position by the truck parts 23 when in their raisedposition on the track. Hence as the rolls move upwardly over thetype-surface the high-tread truck parts 23 are in the position shown inFig. 6, and the roll 8 is brought into contact with the type-surface inorder to perform its proper function.

It is evident from the foregoing explanation that during the upwardmovement of the rolls on the type-surface the sleeve 17 will moveendwise on the spindle 18, and there will be no endwise movement of theroller 12, which will have only its normal rotary action, the same aswhen moving downwardly over the type-surface. After the roll 8 leavesthe upper edge of the type-surface the truck parts 23 are allowed tomove inwardly by virtue of the grooved or cut-away feature 5 of theframe on each side, and the said truck parts are forced inwardly by thesprings 22, which were placed under tension by the outward movement ofthe truck parts. As the truck part 23 at the right (referring to Figs. 3and 6) is moved inwardly the arm 20 will be returned to its normalposition and drop into place between the hook 9 and the inner extremityof the sleeve 17, thus stopping the endwise movement of the sleeve. Assoon as this occurs the roll 12 will begin its endwise distributingmovement by virtue of the cooperative action of the cam or spiral gearand the pinion 16, and this movement of the distributing-roll willcontinue until the rolls 7 and 8 have moved up and down on the inkdisk,after which the action heretofore described will be repeated. 7

The lower rigid part of the arm 20 is provided at the joint 20 with aprojection 20, which limits the upward movement of the part 20 andprevents it from coming in contact with the pinion 16 during the endwisemovement of the roll 12. As shown in Fig. 8,0ne part of the arm 20 maybe provided with a leaf-spring B, rigidly attached to one part of thearm and engaging a pin C on the other part, the tendency of the springbeing to hold the joint closed.

Having thus described my invention, what I claim is 1; The combinationwith the inking-rolls of a printing-press, of a distributing-rollmounted to engage the two inking-rolls, a pinion fast on thedistributing-roll,a cam-gear mounted to engage said pinion and impart anend wise movement to the distributing roll, a spindle upon which saidgear is loosely mounted, an arm for locking the cam-gear against endwisemovement while the rolls are passing over the ink-disk, and means fordisengaging said arm from the gear whereby the latter is permitted tomove endwise, and the endwise movement of the distributing-roll stoppedas the rolls are passing over the type-surface.

2. The combination with the inking-rolls of a printing-press, of adistributing-roll mounted to engage two of the inking-rolls, a pinionfast on the distributing-roll, a spindle mounted to travel with therolls, a cam-gear loosely mounted on said spindle and provided with asleeve, the connection between 'the gear and the spindle being such thatthe distributingroll or the gear and its sleeve, must move endwise, anarm mounted to travel with the rolls and normally locking the sleeveagainst endwise movement, means for automatically disengaging said armfrom the sleeve to allow the latter to move endwise whereby the endwisemovement of the distributing-roll ceases, and means for automaticallyreturning said arm to its locking position.

3. The combination with the inking-rolls of a printing-press, of anendwise-movable distributing-roll mounted to engage two of saidinking-rolls, a spindle mounted to travel with the rolls, a sleeve looseon said spindle, a camgear. connection between the distributingroll andthe sleeve of the spindle, whereby the one or the other must moveendwise during the operation of the rolls, a device for locking thesleeve against endwise movement, and means for automatically unlockingthe said device and returning it to the locking position atpredetermined intervals, whereby the endwise movement is alternatelyimparted to the sleeve and distributing-roll.

4. The combination with the inking-rolls of a printing-press, of anendwise-movable dis-- tributing-roll engaging two of the inkingrolls, anendwise-movable sleeve mounted to travel with the inking-rolls, acam-gear connection between the sleeve and the distributing-roll wherebythe one or the other moves endwise during the travel of the rolls, anarm mounted to travel with the rolls and arranged to lock the sleeveagainst endwise movement, a high-tread truck part mounted on the thirdinking-roll and movable longitudinally thereon, and a connection betweenthe said locking-arm and the said high-tread truck part whereby theposition of the locking-arm is automatically changed by the action ofthe high-tread truck part of the roll, to control the action of thedistributing-roll.

5. The combination with the inking-rolls of a printing-press, of anendwise-movable distributing roll engaging two of the inkingrolls, and athird inking-roll provided with a movable high-tread truck part, and aconnection between the distributing-roll and the high-tread truck part,whereby the endwise movement of the distributing roll is regulated andcontrolled by the said truck part.

6. The combination with the inking-rolls of a printing-press, of anendwise-movable distributing-roll mounted to engage two of theinking-rolls, a spindle mounted to travel with the inking-rolls, anendwise-movable sleeve mounted on said spindle, a cam-gear connectionbetween the sleeve and the distributingroll whereby one of them mustmove endwise, aj ointed spring-held arm mounted on the hook of the thirdinking roll, and normally arranged to engage the spindle and lock thesleeve against endwise movement, a springheld high-tread truck partmounted on the third inking-ro1l,a projection extending from thelocking-arm to engagement with the said truck part, whereby as the saidtruck part moves in a direction parallel with the axis of the roll, thelocking-arm is shifted for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
